Certain of the deflector blades are formed as sleeves 34 for connectionof the cross bars 15 by bolts 16, to support the deflectorirrevolublyinproper relation to the impeller.

The weight of the mixer, head 12 and connected parts, iscounter-balanced by an adjustable weight 35 sliding in the tubularcolumn 2, and connected to head 12 by a chain 36 running over pulleys 37and 38. The mixer is raised and lowered by a crank 39 on a shaft 40,mounted in bearings 41 in housing 8, and having a sprocket 42 engaginga' chain 43,,which also runs over an upper sprocket 14: and is connectedat one point to head 12.

The head may be releasably locked in position by a clamp, or a set SC1eWl5 threaded into one of sleeves 13 and engaging the corresponding guidebar 11. The screw passes through a slot 46 in housing ,8, and has itshead 47 exteriorly accessible to the operator.

While the apparatusis adapted for a great variety of mixing operations,its utility is sufiiciently explained in connection with paint mixing.measured into tanks or tubs such as 50, these being usually mounted onwheels 51, and two, three or more of thetubs are placed about columnbase 1, which preferably has side recesses to accommodate the tubs, andlocate their centers at a radial distance from the column,correspondingpractically to the radial position of impeller shaft 23.With the mixer elevated above the level of the tub tops, frame 3 isswung around to align the shaft axis withthe center ofone of the tubs ortanks, and the mixer is then lowered, by

operation of crank 39, to a desired (adjustable) vertical position,either near the tank bottom, or at an intermediate or upward positiontherein, depending on the character of materials, or otherconsiderations. The motor is energized to run the impeller at a desiredspeed, and the materials are quickly and thoroughly mixed; the mixer isthen raised, swungover another tank, lowered, and V soon. 7 The tanks ortubs may be changed while mixing is going on in any one of them. Thus byrelatively simple apparatus Iprovide for practically continuous mixingoperations, exchange of tanks or tubs, etc., with obvious convenienceand economy.

When it is necessary to cleanthe mixer, (as for example, when it is tobe used in a different mixture or composition) this may easily be doneby lowering it into a tankcontaining asuitable cleaning liquid. I preferably make the mixer in suchform that it is easily cleaned, andespecially avoid sharp corners when material would accumulate and couldnot easily be dislodged by a brush or scraper. Thus, I provide filletsat where The colors, oils, etc., are

blades 20 join plates 19, and also at the lines of juncture of blades 32and webs 33.

I claim:

1. Mixing apparatus comprising an upright, a mixer arranged to swingabout the upright and also to be moved vertically into and out ofreceptacles arranged about the upright, the mixer comprising a rotaryimpeller and a stationary deflector, and means supporting the deflectorin fixed position relative to theimpeller.

2. Mixing apparatus comprising a column, a frame extending laterallytherefrom and revoluble about. the column axis, a head guidedfor'vertical movement in the frame, and a mixer carried by the head, themixer including a rotary impeller, an upper drive shaft and drivingconnections thereto, and a lower shaft having sliding connection to theupper shaft and connectedto the impeller, and a stationary deflectorabout the impeller and, irrevolubly connected to the head.

3. Mixing apparatus comprising a column, a frame extending laterallytherefrom and revoluble about the column axis, vertical guide bars inthe frame, a head having sliding mounting thereon,,and supporting barsdepending from the head, and a deflector connected to the supportingbars.

4. Mixing apparatus comprising, a column having a base and lower portionadapted for the location of a plurality of tanks about the column, aframe mounted for rotation about an upward part of the column above thelevel of the tanks, guides on the frame, mixing apparatus arranged forvvertical movement on the guides for insertion in any of the tanks whenthe frame is swung to position the mix ing apparatus thereover, drivingmechanism on an upper portion of the frame, and a connection from thedriving mechanism to the mixing apparatus and arranged to admit thevertical movement thereof, the mixing apparatus including a rotaryturbo-impeller and a stationary turbo-deflector about the impeller andvertical struts on which thedefiector is mounted in stationary relationto the impeller. v v

5. Mixing apparatus comprising a column having abase and lower portionadapted for location of a plurality of tanks about the column, a framemounted for rotation about an upward part of the column above the levelof the tanks, guides on-the frame,mixing apparatus arranged for verticalmovement on the guides for insertion inany of the tanks when the frameis swung to position the mixing apparatus thereover, driving mechanismon an upper portion of the frame, and a connection from the drivingmechanism to the mixing apparatus and arranged to admit the verticalmovement thereof, upper and lower sprockets in the frame, a-chainrunning over the sprockets and operatively connected at one point to themixing apparatus, and a crank at one of the sprockets to effect verticalmovement of the apparatus.

6. Mixing apparatus comprising a column having a recessed base and lowerportion adapted for the location of a plurality of tanks close about thecolumn, a frame mounted for rotation about an upward part of the columnabove the level of the tanks, guides on the frame, mixing apparatusarranged for vertical movement on the guides for insertion in any of thetanks When the frame is swung to position the mixing apparatusthereover, driving mechanism including a motor on an upper portion ofthe frame, a connection from the driving mechanism to the mixingapparatus and arranged to admit the vertical movement thereof, a rotaryturbo-impeller and a stationary deflector about the impeller andvertical struts on which, the deflector is mounted in stationaryrelation to the impeller.

In testimony whereof I aflix my signature.
